You don't think that you can tie together "this much of video was buffered and _possibly_ displayed" is useful information? You don't think that "60 seconds of a 10 minute video was buffered and _possibly displayed_, and another 30 seconds of buffer was requested every 30 seconds for 5 minutes" is useful information? You don't think that you can determine that the user stopped watching the video after between four-and-a-half to five-and-a-half minutes of the video had played?
